Bushing, Spigot x FPT (Flush Style) PVC Schedule 80 1-1/2" x 1/2" (838-209)

This 1-1/2" × 1/2" Schedule 80 PVC Flush Bushing delivers a three-step solvent-cement-to-thread size reduction in a single low-profile fitting, transitioning a 1-1/2" slip socket port directly to a 1/2" female NPT threaded outlet. The 1-1/2" spigot end inserts into any standard 1-1/2" slip socket fitting or coupling for solvent cement joining, while the 1/2" FPT end receives a compatible male-threaded fitting, valve, nipple, or instrumentation connection on the reduced side.

The depth of reduction — from 1-1/2" down to 1/2" — makes this bushing a particularly efficient solution for installations requiring a significant size step-down at a slip socket position without stacking multiple fittings in series. Where a shallower-reducing bushing would still require additional reduction downstream, the 838-209 accomplishes the full transition in a single compact component, reducing assembly length, joint count, and potential leak points.

As with all 838-series fittings, the spigot end is the key distinction from the threaded 839-series flush bushings. Rather than threading into a female port, the spigot end solvent cements into a slip socket — making this the correct fitting wherever the receiving component has a slip socket inlet. This enables a 1/2" threaded outlet to be introduced at any 1-1/2" slip socket location in the system without rerouting or adding an intermediate adapter.

The flush style eliminates the protruding hex shoulder of a standard hex bushing, creating a streamlined, low-profile assembly that installs cleanly inside the receiving socket. This is especially advantageous in compact mechanical assemblies where hex shoulder clearance would create interference with adjacent pipe runs, structural members, or enclosure walls.

Manufactured in dark gray Schedule 80 PVC, this bushing provides the increased wall thickness and mechanical strength required in industrial, chemical, and commercial pressure piping where Schedule 40 ratings are insufficient. PVC's broad chemical resistance covers acids, bases, salts, chlorine, and most common process fluids, providing lasting performance in corrosive environments where metal bushings would degrade or introduce contamination. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 630 psi at 73°F (governed by the 1-1/2" spigot end), this fitting handles standard to elevated pressure service across a wide range of fluid handling applications. For the spigot end, clean and dry the spigot exterior and receiving socket interior, apply purple PVC primer to both mating surfaces, then apply a uniform coat of Schedule 80 PVC solvent cement to both surfaces before inserting. Hold firmly for 30 seconds and allow full cure time per the cement manufacturer's guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to all male threads engaging the 1/2" FPT end. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Industrial Process Piping — Introduces a 1/2" threaded instrumentation tap, gauge port, or chemical injection point directly at a 1-1/2" slip socket position on process headers, pump manifolds, and equipment nozzles in chemical processing, water treatment, and manufacturing facilities — eliminating the need for intermediate reducing fittings between the socket and the threaded tap
• Commercial Plumbing — Reduces a 1-1/2" slip socket port on a tee, cross, or coupling to a 1/2" threaded branch at drain taps, pressure gauge connections, fixture supply transitions, and test cock positions in mechanical room and building water distribution piping
• Water & Wastewater Treatment — Provides a compact solvent-cement-to-thread transition at chemical dosing injection ports, sampling connections, and small-bore instrumentation taps along Schedule 80 PVC process headers in municipal and industrial water treatment systems
• Chemical Handling — Delivers a deep-reducing, corrosion-resistant spigot-to-thread transition at tank outlets, reagent distribution headers, and chemical feed lines where the primary piping uses slip socket fittings and a downstream instrument or valve requires a 1/2" threaded connection
• Irrigation & Agricultural Systems — Used where a 1-1/2" slip socket position must feed a 1/2" threaded control valve, fertigation injector, or pressure gauge in commercial irrigation headers, greenhouse distribution manifolds, and agricultural water supply systems
• HVAC & Mechanical Systems — Installed in PVC-piped cooling tower makeup lines, treated water headers, and condensate management systems requiring a Schedule 80 pressure rating with a deep-reducing spigot-to-thread transition at small-bore threaded branch connections
